Sony 46" KP46S55 chassis#SCC-F19-TA....as FREDDIEG suggested I checked resistors on board found all reading good..resoldered some points that looked iffy brought back control on green horz size but not green horz linerity...did find a leg broke on one of the stk's believe it was on IC1705 replaced this chip with one of the original chips that was in set. I now have all controls on convergence board working however I also have a light green line running horizontally across top of screen almost looks like a raster line and it jumps slightly up and down is this still an stk problem or what....does anyone have a schematic of the convergence board in this set i would like to know what the voltages should be and which chips control which colors...Thanks for all the help

ngreene, Check those electrolytic capacitors on the board and see if any are leaky. I normally replace all reg's, if one is bad the others are not far behind.
